把康滇地轴中南段铀矿化划分为砂岩型、钠交代岩型和元古代浅变质岩型三种类型,并阐明其主要特征。明确提出早元古代地壳演化曾经历了原始古陆核形成阶段、沉降活动阶段和基底再固结阶段;明确提出中元古界昆阳群是有别于典型的含较多区域性富铀层位的碳硅泥岩沉积建造。首次对该区部分岩石的原始铀含量进行了研究,有依据地提出了有关岩石可作为该区铀源岩的新认识。明确划分出该区存在的碱性和酸性两大类热液蚀变,指出该区以发育前者的地区成矿前景较好。对该区铀成矿前景明确指出:(1)该区不具备良好的澳加式元古代不整合面型铀矿床的地质条件;(2)非澳加式元古代不整合面的铀成矿前景较差;(3)该区碱(钠)交代岩型铀矿化具有一定的找矿前景。在此基础上遴选出5个相对较好的成矿远景区。
The uranium mineralization in the central-southern axis of the Kangdi-Dian axis is divided into three types: sandstone type, sodium metamorphic rock type and Proterozoic shallow metamorphic rock type, and their main characteristics are clarified. It is clearly stated that the Early Proterozoic crustal evolution experienced the stage of primitive paleocontinent nucleation, subsidence and re-consolidation of the basement. It is explicitly proposed that the Middle Proterozoic Kunyang Group is different from the typical rich uranium layer Bit of carbon-silicon mudstone sedimentary construction. For the first time, the original uranium content of some rocks in the area has been studied, and some new understandings about the rock as a uranium source rock in this area have been proposed. The two types of basic and acidic hydrothermal alteration in this area are clearly divided. It is pointed out that the area has the better prospects of mineralization in the former area. The prospect of uranium mineralization in this area is clearly pointed out: (1) The area does not have the good geological conditions for the Macadamia unconsolidated uranium deposit; (2) uranium mineralization of the non-Australasian unconformity surface Poor prospects; (3) the area alkali (sodium) metamorphic rock-type uranium mineralization has a prospect of prospecting. On this basis, five relatively good prospecting prospects are selected.
